LOL!!!
Amazon is out of stock... but it's only $441 on sale, while CRC has it, but it costs $442. Bottom line is that it was published in 1993, so its already pretty significantly out of date, but, the CRC intro probably says all that most people would care to know anyway, while pointing out that the CBMM's "secrets" aren't all THAT secret... if you've got $444 to spend on getting them:
Addresses all aspects of niobium from its properties and applications to refining and consolidation
Uses many diagrams, photographs, flowcharts, graphs, and tables to illustrate key concepts and data
Provides an extensive reference list
Includes a fascinating summary of the long journey niobium travels from its initial removal from the earth's crust to its finished form
Summary
The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.
